Noticed the little princess was getting lousy gas mileage; ran through the PCM data to discover it wasn't reaching 4th gear; I can command 4th gear in the Override mode but it won't shift there on its own...haven't checked the trans fluid yet; just replaced the A-B solenoids a few months ago...any thoughts (besides trading, at 136k)? Thanks!

Sounds like you are saying you can force an upshift using overrides and the trans upshifts. If that is the case then I would check the value for trans temp, TPS and VSS to see if they make sense. Sounds like a PCM, wiring, sensor problem that causes 4th not to be commanded.

Thanks for the suggestions! Just checked the fluid which is full and a nice color but foamy...will update...

Trans temp was about 43 (engine temp about 199, outside temp about 30F); Transaxle Pressure Switch reads correctly; Vehicle Speed Sensor reads a bit slower than the speedo...I'm leaning (praying) toward a loose connector due to sudden warming we've had here...
